Increasing pollution of the environment causedby heavy metals is becoming a significant problem in developing cities. Species andcultivars of plants for urban plantings shouldexhibit tolerance to these pollutants, andwhat is even more significant, through their absorption they shouldred uce the level of environmental contamination. The aim of the research was to determine whether Berberis thunbergii (DC.), which was grown in the immediate vicinity of roads, developed mechanisms limiting harmful effects of accumulating heavy metals. The mechanism for heavy metal resistance, involving the generation of phytochelatins (PCs), was investigatedin relation to As, Cd, Cr, Co, Cu, Hg, Ni, Pb andZn accumulation. Levels of thiols, i.e. glutathione (GSH) andphytochelatins (PCs), increasedin plants grown in pollutedareas in the city of Poznań in comparison to a residential site (control) and it was related to the activity of phytochelatin synthase (PC-synthase) andthe accumulation of metals. The results indicate that in Berberis thunbergii growing in the polluted urban environment a defense mechanism adapting the plant to potentially adverse conditions was initiated.

Flavonoids are polyphenolic compounds commonly found in plants and they play an important role in stress tolerance. They have the capacity to chelate heavy metals andscavenge free radicals. Urban pollution causes oxidative stress in plants and flavonoids may protect cells against the negative effect of free radicals. In this study levels of anthocyanins andflavonols and4-coumarate:CoA ligase (4CL) activity were determinedin Berberis thunbergii (DC.) plants grown in pollutedandresid ential areas in the city of Poznań. The results showedsignificantly higher accumulation of anthocyanins andstimulation of 4CL activity in plants from the contaminatedsites in comparison to the control plants. Probably the activation of the phenylpropanoidpathway was a response to stress caused by urban pollution.

One-year-old cuttings of basket willow (Salix purpurea × viminalis) were cultivated hydroponically under increasing Cu concentrations (0, 1, 2 and 3 mM) and at four Ca/Mg ratios (4:1, 1:10, 20:1 and 1:¼). After 14 days, rhizosphere and leaf samples were analysed. Salix plants were able to release relatively high amounts of low molecular weight organic acids (LMWOAs) in a short period of time. The total amount of LMWOAs increased with increasing Cu concentrations. Oxalic and acetic acids were dominant, and act as complexing agents for Cu ions, and therefore, organic exudates should be taken into account in phytoextraction of polluted areas. The Ca/Mg ratio of the medium significantly influenced not only concentration, but also the composition of LMWOAs. Phenolics content in leaves increased with the excess of Ca and Mg and with Cu level in the medium for all Ca/Mg ratios. The accumulation of glucose, fructose and sucrose in leaves was observed for deficiency and excess of Ca and/or Mg and Cu treatment at all Ca/Mg ratios. Excess calcium (Ca/Mg = 20:1) led to strong induction of salicylic acid biosynthesis, probably resulting from enhanced oxidative stress.

This work reports a part of hydroponic experiment results concerning changes in Salix viminalis L. cv. ‘Cannabina’ morphology and physiology under stress conditions with different copper concentration levels and verifies our earlier results about the role of different Ca/Mg ratios in trace elements’ accumulation efficiency. In this part, we present the copper accumulation and changes in willow biomass. Concentration of copper in roots, rods, shoots and leaves was analyzed with flame atomic absorption spectrometry. Selected indices characterizing copper accumulation and plant biomass structure were calculated to estimate the potential of willow to remove metal from polluted solution. Our results indicate a general increase of copper accumulation by selected willow organs with increase of copper concentration in modified Knop’s medium. Moreover, significant differences in copper phytoextraction between plants under different Ca/Mg ratios were affirmed (1:10[4:1[20:1[1:1/4).

The aim of the present study was to determine the effect of various Zn application levels on some physiological, morphological and biochemical parameters of a hybrid Salix purpurea 9 triandra 9 viminalis 2. Plants were cultivated under control conditions with application of Zn in the range 0–5 mM. The effects on net photosynthesis rate (PN), stomatal conductance (gs), transpiration rate (E), intercellular CO2 (Ci), chlorophyll a and b, carotenoids, growth, sugars and phenols were analysed. Our investigations confirmed a dual role of Zn, with benefits at the level 1–2.5 mM, and a decrease of measured photosynthesis activity, carbohydrates and chlorophyll below and above this range. Moreover, the decrease of these parameters at the highest Zn application did not reach the level of control plants. This means that this species may have further potential as an accumulator in polluted areas. However, phenols revealed a continuous increase together with Zn increase in the medium.
